摘要
研究了一类可表示为分配格的幂等半环,即加法半群为半格的乘法带半环;通过Green-D关系,得到了加法群为半格的乘法带半环的若干性质;证明了如果半环S的加法半群是半格,则S是乘法带半环当且仅当S是分配格;从而获得分配格结构的一种刻画。
A class of idempotent semirings which can be showed distributive lattice,i, e. , multiplicative band semirings which additive reducts are semilattice are studied in this paper . Some properties of multiplicative bond semirings are obtained by Green-D relation. We also proved S∈S,S is multiplicative band semirings if and only if S is distributive lattice. The characterization for structure of distributive lattice is obtained.
